Bundle Size

Initial bundle size*

Client - Request - Server - Resource - Client - Unzip - Execute - Paint

  • Initial load should be < 400 KB 
  • Dynamic loading, Lazy load parts of your application when needed.
  • Route level or component level code-splitting
  • G-Zip or brotli compression.
  • Differential Bundling
  • Send only the JS that is being used for the initial paint of the web-page.
